Answer:

I had read that when light enters a glass( or any other medium) its speed changes which lead to the bending of its path. But why doesn't light bend when it is incident normal to the surface. It is still entering a new medium and likewise, its speed will change but why doesn't it refract then? I just can't understand it!

Answer:

When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero
